Review of literature on eco-friendly sandwich structures made of non-wood cellulose fibers

In recent years, concerns about environmental pollution have led to the development of natural fiber sandwich structures as alternatives to petroleum-based ones. This paper reviews various studies on sandwich structures composed of non-wood cellulose-nature fibers. These fibers mainly include flax, hemp, jute, kenaf, sisal, coir, and bamboo. The studies are classified based on the type of fibers, the components in which they are used, and experimental tests/numerical investigations. Furthermore, a few suggestions for future research in the field of eco-friendly sandwich structures are made.
